Report New Spotify Web Player not working in MX5 in Maxthon Support & Discussion Posted October 13, 2017 · Edited October 13, 2017 by joemax On 10/11/2017 at 7:24 AM, 7twenty said: And there it is... So it looks like the installer version auto-downloads the widevine DRM components which allows it to play. For whatever reason the same doesn't happen with portable. Why that is the case i'd be interested to know. Maybe because the portable version doesn't have access to spotify web helper???? Edit: If I disable Spotifywebhelper on start up, I can't get Spotify to play.
